Designo R3 Wohndachausstieg

An essential solution when an easy exit to the roof is needed

Side-hung roof access window

Designo R3

The Designo R3 side-hung roof access window is essential wherever craftsmen need an easy exit to the roof – without compromising comfort. The sash of the window opens to the side (left or right-handed opening). The escape roof window can be successfully used in living areas as it is equipped with heat insulating glazing protecting the room from overheating in the summer and heat loss in the winter.

Benefits in a nutshell



The window opens at a 90° angle – comfortable roof access for roofers and chimney sweeps during conservation works.


Easy operation

One-handled operation. Left or right handed opening.


Energy efficiency

It can be used in residential rooms thanks to the same insulation properties as in standard roof windows.


Additional protection

It has been developed with an anti-slam function which protects the window against being slammed shut accidentally caused e.g. by a draught.


Energy balance

The pre-installed thermal insulation WD block is an option that gives even 15% better energy balance of the roof window.


Accessories in use

Interior roller blinds can be used.
